I get this error in firefox, it doesn't work for me in IE either.
Code:
Error: [Exception... "Component returned failure code: 0x80004003 (NS_ERROR_INVALID_POINTER) [nsIDOMNSHTMLDocument.queryCommandState]" nsresult: "0x80004003 (NS_ERROR_INVALID_POINTER)" location: "JS frame :: http://www.myforum.com/clientscript/vbulletin_textedit.js?v=364 :: anonymous :: line 1469" data: no]
